PURPOSE: A bag for a motorcycle is provided to be easily exchanged and to have excellent adhesion, because of a suction unit combined with a combining surface by a tightening stopper. CONSTITUTION: A bag for a motorcycle comprises a suction unit. In the suction unit, a sucking plate(21) attached to a flat surface. A fixing member(23) is inserted into the center of the sucking plate, and a screw-protrusion is projected. A tightening stopper(24), which is combined to the screw-protrusion, forms a projected edge toward the top of the sucking plate edge. The tightening stopper comprises a groove edge in order to inserting the projected edge upwardly. A penetration groove exposing the screw protrusion is formed in a cap. By tightening the tightening stopper, thereby the edge of the sucking plate is attached to floor, and only the center part is risen, thereby generating vacuum condition, and strengthening adhesion.
